SPECIFICATION forming part of Letters Patent No. 500,513, dated .Tune 27, 1893.

Application filed March 24, 1 8 93.

To all whom, it may concern:

3e it known that I, NEWTON O. SAMPLE, a citizen of the United States, residing at the city of Philadelphia, in the county of Phila.- delphia and State of Pennsylvania, have inyented certain new and useful Improvements 1n Plows, of which the following is a specification.

The principal objects of my invention are first, to provide a light, strong and comparatively 'inexpensive plow-beam 5 second, to provide simple and efficient means for attaching the end of the beam to the frame-work of the plow in such manner that the beam may be adjusted in respect to the plowsh'are; third, to provide simple and efficient devices for supporting a spring between the clevis and the plow-beam, in order to relieve the team of undue strain in the event of the plowshare becoming wedged or otherwise impeded; and fourth, to provide compact means, whereby the clevis may be slightly turned about the horizontal axis of the beam in order to change the line of draft toward the right or left, so that the width or depth of the furrow slice may b e increased or diminished as required.

My invention Vconsists of a plow provided with a channeled beam of U-shape in cross section having webs 4ranging transversely of the channeled portions and having reinforcing ribs.

My invention further consists of a plow provided with a channeled beam having a slotted projection adapted for attachment to the frame-work of the plow and having a rib for reinforcing the union of the channeled portion of the beam and slotted projection.

`My invention further consists of a plow provided with a beam having a cavity or bore in its front extremity, a spring fitted in said cavity or bore, a cap fitted over said extremity and provided with a clevis, and a pin engaging the spring and cap and afforded a range of movement in slots in the walls of said cavity or bore.

My invention further consists of a plow provided with a beam having a cylindrical recessed extremity, a spring mounted in said recessed extremity, a cap rotatably mounted on said cylindrical extremity and provided With a clevis, and a pin working in longitudi- Serial No. 467,459. (No model.)

nally ranging slots or openings in the wall of the recessed extremity and adapted to engage the spring and one of a series of notches ranging transversely of the opening in the cap.

My invention further consists of the improvements in plows hereinafier described and claimed.

The nature, characteristic features and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof; and in which-- Figure l, is a perspective view showing the moldboard and rear portions of a plow embodying features of my invention. Fig. 2, is a central section of the beam embodying the features of my invention. Fig. 3, is a top or plan view of the extremity of the beam showing the clevis in vertical position. Fig. 4, is a top or plan view of the extremity of the beam showing the clevis slightly turned in order to adjust the width of the furrow slice; and Fig. 5, is a detached view drawn to an enlarged scale of the clevis retaining pin.

In the drawings, the land-sideamold-board b, and the lower extremities of the hands c, are attached to the frame of the plowshare d. This frame is provided with an upwardly projecting post a', and with a rearwardly projecting brace a2. The beam e, is bolted to the post a', and is provided with a projection e', having a'depending lip e2, that engages the brace a?, as illustrated inFig. l, in order to impart strength to the construction. The projection e', is adjustably secured to the top of the brace a2, by means of a set-screw c3, that engages the brace a2, and works in a slot e4, in the projection e', so that the beam'e, may be turned about the post a', to adjust the width of the furrow slice and then clamped to place by means of the set-screw e3. The beam c, is preferably made of metal and in such case is channeled along its under side, as at e5, Fig. 2, and is U-shaped in cross section, in order to lighten its Weight without materially diminishing its strength.

e6, are webs ranging transversely of the channeled portions e5, of the beam e, and 1ocated near the points of connection of the post a', and colter f, with the beam e, in order to impart additional rigidity to the latter.

IOO

or recess es, for the accommodation of a spiral spring s, which by yielding serves to relieve the team of undue strain in the event of the io plow becoming wedged or otherwise stopped` as will be hereinafter more fully explained.

The spring s, may be readily inserted into the channeled portion of the beam and then fitted y into the recess e8.

g, is a cap fitted onto the cylindrical portion of the end of the beam and provided with a clevis g', to which the draft is applied. For the sake of lightness portions of the curved walls of this cap g, lnay be cut away as shown at g2, Fig. 4.

h, is-a pin afforded a range of movement in openings e9, disposed longitudinally of the cylindrical portion of the beam e, and adapted to engage a washer or gasket t', that rests upon the rear end of the spring s. The ends of this pin h, work in transversely ranging opening g3, in the wall of the cap g, and are respectively adapted to engage a series of notches g4, cut or otherwise formed in the rear edges of the openings g3, so that the cap g, and clevis g', may be turned in respect to the beam in order to shift the line of draft to the right orto the left. In the present instance the pin 7L, is provided with a head h', a square end h2, and a feather h3, Fig. 5, adapted to work in the notches g4, as will be hereinafter more fully explained.

j, is a gage-wheel journaled to bracketsj, secured to portionsj", of the beam which are built out and iattened for their reception.

c', is a spanning-rod that serves to brace the upper portions of the handles c.

The mode of operation of the hereinabove described plow is as follows:-In the event of the plow becoming wedged or otherwise stopped, the recoil is taken up by the spring s, and the team is relieved of undue strain. Under these circumstances the pin h, moves forward through the slots e9, in the curved walls of the cylindrical end of the beam e, thus permitting the team to draw the cap g, forl ward for a short distance against the force of the spring s, and until the team can be stopped, in order to permit the plow-man to free the plow. The width of the furrow slice may be increased or diminished by loosening the setscrew e3, and turning the beam e, around the post a as a center towards the right or left as may be required and then clamping it in such position by means of the set-screw. This result may also be accomplished by turning the cap g, in respect to the cylindrical portion of the beam e, as shown in Fig. 4, so that the i upper and lower portions of the clevis g', may be shifted toward the right or left, whereby the line of draft is transferred. In order to turn the cap g, the pin 7i, is caused to disengage one of the notches g4, and is then caused to engage another of the notches g4, in order to maintain thecap in position after it has been turned. The pin h, may be readily caused to disengage one of the notches g, by turning the pin h, by means of a wrench or key applied to the square head h2, in such manner that the feather h3, is turned out of one of the notches g4, and after the cap g, has been turned luto the required position the pin h, may be caused to engage another of the notches g4, by turning the pin h, by means of the wrench or key in such manner that the feather h3, is turned into the other of the notches g4. By this arrangement the pin may be readily and rapidly transferred from one notch to another.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-
